Calling a sheet object in a variable

[#1]

I asked this question in another thread, but it deserves it's own thread, I think.

Is there a way to point to an object ID, and then a column in that object, in a variable?

Something like:

= (ObjectID(ColumnNumber)) ?

Hi,

You can try with getcell function..

I am not yet tried it.

This below example I got it from API guide:

set table = ActiveDocument.GetSheetObject( "CH01" )

for RowIter = 0 to table.GetRowCount-1

    for ColIter =0 to table.GetColumnCount-1

        set cell = table.GetCell(RowIter,ColIter)

        msgbox(cell.Text)

    next

next

By writing macro , Its working..

Sub StraightTableCell

set table = ActiveDocument.GetSheetObject( "CH01" )

        set cell = table.GetCell(1,1)

        msgbox(cell.Text)

End Sub

Karthiks, could you break down exactly what that is doing?

I have a straight table called "RC", and the field is "column(10)", if you can possibly use that info and show me how to do it?

[#5]

Here's a picture of the table I'm referring to.

See the "RC02 Min Percentage" cell? That does a calculation to determine the lowest percentage value of all the values in the table.

I need to call to that, in a bar chart. I have about 10 of these straight tables, and I need to show each table's lowest percentage value inside of the bar chart.

I'm hoping there's a way to set a variable to that table's cell (which is called column(10)), and then call the variable inside of the bar chart.

[#6]

I guess my question is, how does the variable know which table I'm talking about?

In the "RC02 Min Percentage" column, the expression just says "if ((Column(3)<=Column(5)), Column(3), Column(5))"... It's a simple if statement to pull the min value down.

If I put that in the variable, it won't know which of my 10 tables I'm talking about. They all have columns.

Is there a better, more distinct way to do the min, that the variable would know which fields I'm speaking of, in which tables?

It doesn't. If you want to reuse an expression don't use column references. Use variables that are chart (-layout) independant. For example:

vExpr1: sum(Value1)

vExpr2: sum(Value2)

vExpr3: rangemax( $(vExpr1), $(vExpr2))

Column3: $(vExpr1)

Column5: $(vExpr2)

RC02 Min Percentage: $(vExpr3)

An expression in some other chart: $(vExpr3). If that chart uses the same dimensions it will return the same value.

edit:

The $ is to force evaluation of the variable. It's called dollar expansion. You can see how that works by trying it out in a text box =vVariance versus =$(vVariance).

okay I think I see what you're saying - could you humor me, and tell me how I would set it up, in my example?

I'm pretty confused when it comes to variables and how to set them up, and I'm only about 2 weeks new to Qlikview. lol.

Would I make a variable for column 3 and 5, and put the same expression I now have in those columns inside of the variable?

Does the $ make the variable know it's a value I'm returning, I think?

Then, I can call to the variable in my bar chart, and return the value in the variable?

Thanks a ton for this, by the way.
